OFCOM will never view this as a 'material detriment' to Plusnet users under General Condition 9.6, as Plusnet are not modifying the contractual conditions.
I think this is likely the correct interpretation.
The terms of a contract are what an reasonable third party believes the parties agreed to prior to the formation of the contract (
Smith v Hughes (1871) LR 6 QB 597).
Most of what the parties agreed to will be the explicit terms of the contract. I've looked through
Plusnet's residential terms and conditions, and can see nothing relating to telephone support hours.
There are a limited number of scenarios where terms can be implied into a contract.
The most common implied terms scenario is when terms are implied by statute, such as the well known Sale of Goods Act 1979 implied terms (which apply to contracts for the sale of goods only) and the similar but somewhat less well known Supply of Goods and Services Act 1982 implied terms (which apply to contracts for the supply of services with or without the sale of goods in the same contract).
In a limited range of scenarios, terms can be implied by the courts.
When there are repeated contracts between the parties, it is possible for terms consistently appearing in post-contractual documentation to become implied into later contracts (as in
Spurling v Bradshaw [1956] 1 WLR 461). This scenario does not appear to have any relevance here, as consumers will typically have no more than one new contract every 12 months with Plusnet. Moreover, unless there is something I am unaware of as a non Plusnet customer, no post-contractual promise by Plusnet to provide telephone support at certain hours for the duration of the contract is included in the documentation you receive after entering into a contract - there is merely notification of the current opening hours on the Plusnet web site and, presumably, if you phone for support out of hours.
Other scenarios where terms have been implied by the courts include terms to clarify the presumed shared intention of the parties, though in the leading case I'm thinking of (
Attorney General for Belize v Belize Telecom Ltd [2009] UKPC 10) the Privy Council made it clear that implied terms cannot improve upon the contractual agreement between the parties.
I cannot therefore see any justification within general contract law to imply terms relating to support hours into Plusnet's contract. The statement on Plusnet's web site that residential support hours are currently 24/7 doesn't amount to any sort of promise by Plusnet to continue providing 24/7 support, let alone a promise to anyone entering into a new contract by Plusnet that would therefore form an explicit contractual term on support hours.
In contracts for the provision of certain regulated telecommunications services, Ofcom imposes a requirement to embody some general conditions under the Telecommunications Act 2003. These
General Conditions include General Condition 9 imposing certain minimum requirements for the terms of telecommunications contracts.
GC 9.2(f) requires contracts to include terms detailing:
the types of maintenance services and customer support services offered, as well as the means of contacting these services
though this does not appear to extend to a requirement to specify the opening hours of any support services provided under the contract. Obviously, any explicit contractual term specifying support hours is likely to bind the provider to provision of support services for the specified hours at a minimum.
I believe that Plusnet's specification of 'helpdesk services' (without further definition) in the
first clause of the various product specific terms meets GC 9.2(f).
As has been noted, GC 9.6 imposes a requirement to give one month notification of changes to contractual terms amounting to material detriment, and for subscribers to be given the right to contractual termination without penalty if they do not accept the detrimental change.
There was a clarification of GC 9.6 when mobile phone operators began applying price hikes 'in line with inflation'.
Indeed, Ofcom issued
guidance about when a price increase would represent a material detriment. That guidance is unhelpful here, as it relates solely to price changes.
It is difficult to see how GC 9.6 is engaged by a change in support hours, considering that there is nothing in the contractual terms specifying when Plusnet's helpdesk is open.
If Plusnet were to reduce the telephone helpdesk hours so severely that it could be argued that there was not a meaningful telephone helpdesk service any more, there is an argument that Plusnet would breach the contractual requirement to provide helpdesk services. However, I find it difficult to see that the purported change goes as far as to amount to removal of helpdesk services. The new opening hours are still much longer than many residential helpdesks.
Relatively few contractual terms are conditions, which give a right to repudiate and terminate the contract on breach. The well known Sale of Goods Act 1979 terms about fitness for purpose, reasonable quality and conformation with description are notable exceptions, as they are specified as conditions in the Act which is why they are so powerful.
In most cases, terms are silent as to whether they are conditions (right to repudiation on breach) or warranties (never giving rise to the right of repudiation). In some cases it is still possible to classify the term as a condition or warranty, though unspecified terms are usually innominate terms. Breach of an innominate term requires the innocent party to be deprived of "substantially the whole benefit" of the contract (
Hong Kong Fir Shipping v Kawasaki Kisen Kaisha [1962] 2 QB 26) before the right of repudation on breach exists. As the main subject material of the Plusnet contract is telecommunications services, it is doubtful that any restriction in helpdesk hours would deprive the customer of "substantially the whole benefit" of the contract, at least in any general sense.
There may be situations where a service failure together with the restricted availability of the helpdesk amounts to deprivation of "substantially the whole benefit" of the contract, giving the consumer the right of termination - though in this scenario the right of termination would follow almost entirely from the unresolved failure of services, not the limited helpdesk hours. It is possible for the right to renunciation to exist following an anticipated breach of contract, but such an anticipated breach must be clear and absolute to give rise to the right to renounce. The right to renounce based on unresolved service failure therefore seems unlikely to exist in any anticipatory scenario, as there cannot be certainty about future breakdown affecting service provision.
